When calculating the radar cross section (RCS) of electrically large complex objects with computational electromagnetics tools, computer aided design models of the objects are required. Guidelines regarding the level of fidelity with which the models need to be constructed to achieve specific levels of accuracy, however, remain unclear. In this paper the(More)
The matching required between the two directions through a retrodirective cross-eye jammer is considered using both the traditional phase-front analysis and an extended analysis. The design parameters to achieve a specified tracking error are derived and an optimal design is proposed. The results for the extended analysis show that the tolerances required(More)
The skewness in the peaks of the two-dimensional power spectral density (PSD) using the quadrant regions of support is investigated. In practice, limited data records or deviation from the assumed white noise hypothesis causes non-ideal approximations in the autoregressive process. If only a limited number of data samples is available, the correlation(More)
Conventional rectangular waveguides are commonly used for high power and other microwave and millimeter-wave applications. Their use at lower frequencies has been limited by their bulky nature. A new type of compact waveguide called a partial H-plane waveguide has previously been proposed that has only one quarter of the cross-sectional area of a(More)
